Hello,all of my steemit friends how are you all?I am fine today.I am Wasim Khan Sujon.I am a Bangladeahi but I live in South Korea.Today I want to share an invention before age.
There are many inventions before computer age.Among these,the one that is most noteworthy is the is the invention of telephone.Although we take it for granted,now a days it is unthinkable of our life without it.
Telephone is a very simple instrument to use.There are certain digits on the set.All we have to do dial these numbers.The reason this inventon came about is to talk to a person wothout visiting him.Before telephone if we have to talk to somebody we have to be present in front of him physically.But,telephone has removed the barrier.
Telephone has many advantages.First of all it has removed the physical barrier.We can talk to anybody anywhere anytime in the world.Also,there are certain disadvantages.Telephone can be misused .It should be used only when necessary.Sometimes,it is used without being required.Also,young people spend a lot of time using it.
It can be harmful for them.
